Definitions
- the present invention refers to a plug and heating element assembly for a diffusing device for volatile substances.
- a diffusing device of the heating type generally comprises a heating element consisting of a plastic or ceramic support in which electrical resistances which heat up when passed through by an electrical current are inserted.
- the heating element is coupled to a wick immersed in a solution to be diffused, contained in a containing shell, or to a tablet impregnated with the solution to be diffused.
- the electrical resistances of the heating element are connected by means of electrical wires to the poles of an electrical plug able to engage in an electrical socket connected to the supply main.
- the body of the electrical plug must be coupled with the body of the containing shell which must enclose the heating element.
- the heating element and the plug are connected to each other only by electrical wires. Since said electrical wires are flexible, the heating element has a great freedom of movement with respect to the plug. As a result, the mechanical coupling between the plug and the container shell proves somewhat complex and laborious.
- the heating element has three degrees of freedom with respect to the plug and can therefore move in any direction during the handling and the transport of the plug and heating element assembly.
- EP 716 807 discloses an evaporator heater comprising an electrical heating element connected to a plug by a stem, integral to the heating element, to which the plug is rotatably snap engaged, said stem remaining in place when the evaporator heater is assembled.
- EP 945 062 discloses a vaporizer with an electrical heating element connected to a rotatable plug in different ways, the means connecting the rotatable plug to the electrical heating element remaining in place when the vaporizer is assembled.
- Object of the present invention is to eliminate the drawbacks of the prior art by providing a plug and heating element assembly for a volatile substance diffusing device that is simple to assemble, also with the use of robotised machines.
- Another object of the present invention is to provide a plug and heating element assembly for a diffusing device that is economical and not bulky and that does not require an excessive use of additional parts or elements.
- the plug and heating element assembly for a volatile substance diffusing device comprises:
- the heating element is designed to be disposed near to or in contact with a tablet or a wick impregnated with volatile substances to promote diffusion of said volatile substances.
- At least a bridge connecting said body of the plug to said body of the heating element is provided, so as to avoid a relative translation of the plug body with respect to the heating element body.
- the plug and heating element assembly can easily be mounted in the outer shell of the diffusing device, without problems of relative movements of the heating element with respect to the plug.
- This assembly is indicated as a whole with the reference numeral 1 and comprises a heating element 2 and a plug 4.
- the heating element 2 comprises a support or body 20 which can be made of plastic, of ceramic material or of any other electrically insulating material with characteristics of heat resistance and heat conduction.
- the support 20 is shown in a parallelepiped shape but it can also have a cylindrical or another shape.
- the support 20 of the heating element 2 comprises a cylindrical tang 22 which defines a circular hole 21.
- a cylindrical wick (not shown) that is immersed in a volatile solution contained in a containing shell (not shown) is inserted in the hole 21 of the heating element 2.
- the heating element can have a seat to receive a tablet impregnated with the substance to be diffused and in any case the heating element is destined to be positioned near to or in contact with a support impregnated with the substance to be diffused.
- the resistances 23 can be locked in position by cementing into the support 20, or by using other sealing materials.
- the plug 4 comprises a body 40 generally of insulating plastic which has housings in which conducting poles 41 are disposed.
- a body 40 generally of insulating plastic which has housings in which conducting poles 41 are disposed.
- conducting poles 41 are disposed.
- two cylindrical poles are shown in the figures; however, it is obvious that according to the standards in force in the different countries, the plug 4 can also have flat poles or three poles.
- the poles 41 of the plug 4 are connected by means of electrical cables 42 to the respective resistances 23.
- the wire strands of the electrical cables 42 are covered with an insulating sheath.
- the body 40 of the plug has at its rear end a circular flange 43, disposed along a plane at right angles to the axis of the poles 41. Along the perimeter of the circular flange 43 a groove 44 is formed.
- the plug 4 is able to couple rotatably with the outer shell of the diffusing device.
- the outer shell has a circular hole defined by a circular frame that engages rotatably in the groove 44 of the flange 43 of the plug. In this manner the outer shell can be rotated with respect to the plug, so that the wick is always oriented in a vertical position, regardless of the orientation of the socket that receives the plug, to avoid possible leakage of the solution from the container shell.
- a bridge 5 is connected to the front edge of the support 20 of the heating element 2 and protrudes forward therefrom.
- the bridge 5 can take the form of a straight rod 50 with a reinforcing rib 51.
- the bridge 5 has at its free end an abutment flange 53 from which a cylindrical pin 54 protrudes forward ( Figures 3 and 4 ).
- the bridge 5 can be made in a single piece with the support 20 of the heating element, for example by injection moulding. Alternatively, the bridge 5 can be made integral with the support 20 of the heating element in any other manner, such as by welding, by gluing, by forced coupling and the like.
- a cylindrical seat 45 ( Figures 3 and 4 ), designed to receive in a rotating coupling relationship the cylindrical pin 54 of the bridge 5, is formed in the rear wall of the body 40.
- the cylindrical pin 54 of the bridge is inserted in the cylindrical seat 45, until the abutment flange 53 of the bridge abuts against the rear wall of the plug 4 around the cylindrical seat 45.
- the heating element 2 and the plug 4 are constrained to each other with two degrees of freedom. That is to say, the heating element 2 can rotate only with respect to the plug 4, around the axis of the pin 54. Thus any translating movement of the heating element 2 with respect to the plug 4 is prevented by the coupling of the pin 54 of the bridge inside the cylindrical seat 45 of the plug.

- a bridge 5, substantially the same as that of the first example, is coupled rotatably to the plug 4.
- a rectangular plate 150 which extends upward on a plane at right angles to the plane of the poles 41 of the plug is connected to the bridge 5. The top end of the plate 150 is fixed to the front surface of the body 20 of the heating element.
- the plate 150 can be made of plastic material and coupled to the bridge 5 fixedly or rotatably.
- a printed circuit board 151 on which is mounted a switch 152 that can be operated by the user, is fixed on the plate 150.
- Other optional devices, such as light devices (LED, lamps) and/or timers can be mounted on the circuit board 151.
- the heating element 2 comprises a parallelepiped body 20 inside which the electrical resistances 23 are disposed.
- Two seats 230 substantially U-shaped in cross-section, able to receive and to guide the electrical wires 42 from the poles 241 to the resistances 23, protrude from the body 20.
- the body 20 has a circular connection 229 in which a cylindrical tang 222 defining a hole 221 to receive the wick is mounted rotatably.
- the tang 222 acts as a heat regulating element and for this purpose it has a slot 228 for the passage of the heat from the resistances 23 to the wick. In this manner, the flow of heat toward the wick is regulated by rotating the tang 22.
- two outer shell halves 207, 208 are mounted on the assembly 200.
- the first shell half 207 is coupled rotatably to the flange 43 of the body of the plug 4 and the second shell half 208 is coupled to the heating element 2 and to the first shell half 207.

- a hole 210 to favour the diffusion of the volatile substance is formed in the front surface of the shell half 208.
- Assembly of the diffuser device is extremely simple and can be done automatically, precisely because the heating element is fixed integrally to the plug.
- the weakened part 206 of the bridge 205 is cut with a tool so that the heating element is free from the plug and can therefore rotate with respect to the plug according to the arrangement of the electrical socket.

Description
- The present invention refers to a plug and heating element assembly for a diffusing device for volatile substances.
- A diffusing device of the heating type generally comprises a heating element consisting of a plastic or ceramic support in which electrical resistances which heat up when passed through by an electrical current are inserted.
- The heating element is coupled to a wick immersed in a solution to be diffused, contained in a containing shell, or to a tablet impregnated with the solution to be diffused. The electrical resistances of the heating element are connected by means of electrical wires to the poles of an electrical plug able to engage in an electrical socket connected to the supply main. To complete the assembly of the diffusing apparatus, the body of the electrical plug must be coupled with the body of the containing shell which must enclose the heating element.
- Thus the heating element and the plug are connected to each other only by electrical wires. Since said electrical wires are flexible, the heating element has a great freedom of movement with respect to the plug. As a result, the mechanical coupling between the plug and the container shell proves somewhat complex and laborious.
- In fact, we must consider that the heating element has three degrees of freedom with respect to the plug and can therefore move in any direction during the handling and the transport of the plug and heating element assembly. As a result, it is difficult to use robotized machines to assemble the plug to the containing shell, since these robots do not know the relative position of the heating element with respect to the plug.

EP 716 807 -
EP 945 062 - Object of the present invention is to eliminate the drawbacks of the prior art by providing a plug and heating element assembly for a volatile substance diffusing device that is simple to assemble, also with the use of robotised machines.
- Another object of the present invention is to provide a plug and heating element assembly for a diffusing device that is economical and not bulky and that does not require an excessive use of additional parts or elements.
- These objects are achieved, in accordance with the invention, with the characteristics listed in appended
independent claim 1. - Advantageous embodiments of the invention are apparent from the dependent claims.
- The plug and heating element assembly for a volatile substance diffusing device comprises:
- a plug comprising a body in which conducting poles for the connection to an electrical socket are mounted, and
- a heating element comprising a body in which at least one electrical heating resistance, connected by means of electrical wires to the poles of the plug, is disposed.
- The heating element is designed to be disposed near to or in contact with a tablet or a wick impregnated with volatile substances to promote diffusion of said volatile substances.
- According to the invention at least a bridge connecting said body of the plug to said body of the heating element is provided, so as to avoid a relative translation of the plug body with respect to the heating element body.
- In this manner the plug and heating element assembly can easily be mounted in the outer shell of the diffusing device, without problems of relative movements of the heating element with respect to the plug.

Figure 12 is a side view showing a third example of a plug and heating element assembly for a volatile substance diffusing device not according to the invention; and -
Figure 13 is a top plan view of the plug and heating element assembly ofFigure 12 . - A first example of a plug and heating element assembly for a volatile substance diffusing device not covered by the claims is described with reference to
Figures 1-4 . - This assembly is indicated as a whole with the
reference numeral 1 and comprises aheating element 2 and aplug 4. - The
heating element 2 comprises a support orbody 20 which can be made of plastic, of ceramic material or of any other electrically insulating material with characteristics of heat resistance and heat conduction. Thesupport 20 is shown in a parallelepiped shape but it can also have a cylindrical or another shape. - The
support 20 of theheating element 2 comprises acylindrical tang 22 which defines acircular hole 21. A cylindrical wick (not shown) that is immersed in a volatile solution contained in a containing shell (not shown) is inserted in thehole 21 of theheating element 2. - Even if specific reference has been made to a wick, it is obvious that the heating element can have a seat to receive a tablet impregnated with the substance to be diffused and in any case the heating element is destined to be positioned near to or in contact with a support impregnated with the substance to be diffused.
- Seats are formed in the
support 20 of the heating element to accommodateelectrical resistances 23 which heat up when passed through by an electrical current. Theelectrical resistances 23 are disposed tightly close to thetang 22 so as to heat it through heat conduction. In turn, thetang 22 of the heating element heats the wick through heat conduction. As a result, the heating of the wick promotes the diffusion of the volatile substances contained therein. - Two
resistances 23 disposed in diametrically opposite positions with respect to thehole 21 and connected in series to each other have been shown in the figures; however, it is obvious that a single resistance or more than two resistances can be disposed in thesupport 20. - The
resistances 23 can be locked in position by cementing into thesupport 20, or by using other sealing materials. - The
plug 4 comprises abody 40 generally of insulating plastic which has housings in which conductingpoles 41 are disposed. By way of example, two cylindrical poles are shown in the figures; however, it is obvious that according to the standards in force in the different countries, theplug 4 can also have flat poles or three poles. - The
poles 41 of theplug 4 are connected by means ofelectrical cables 42 to therespective resistances 23. The wire strands of theelectrical cables 42 are covered with an insulating sheath. - The
body 40 of the plug has at its rear end acircular flange 43, disposed along a plane at right angles to the axis of thepoles 41. Along the perimeter of the circular flange 43 agroove 44 is formed. - The
plug 4 is able to couple rotatably with the outer shell of the diffusing device. For this purpose the outer shell has a circular hole defined by a circular frame that engages rotatably in thegroove 44 of theflange 43 of the plug. In this manner the outer shell can be rotated with respect to the plug, so that the wick is always oriented in a vertical position, regardless of the orientation of the socket that receives the plug, to avoid possible leakage of the solution from the container shell. - A
bridge 5 is connected to the front edge of thesupport 20 of theheating element 2 and protrudes forward therefrom. Thebridge 5 can take the form of astraight rod 50 with a reinforcingrib 51. Thebridge 5 has at its free end anabutment flange 53 from which acylindrical pin 54 protrudes forward (Figures 3 and 4 ). - The
bridge 5 can be made in a single piece with thesupport 20 of the heating element, for example by injection moulding. Alternatively, thebridge 5 can be made integral with thesupport 20 of the heating element in any other manner, such as by welding, by gluing, by forced coupling and the like. - A cylindrical seat 45 (
Figures 3 and 4 ), designed to receive in a rotating coupling relationship thecylindrical pin 54 of thebridge 5, is formed in the rear wall of thebody 40. Thus thecylindrical pin 54 of the bridge is inserted in thecylindrical seat 45, until theabutment flange 53 of the bridge abuts against the rear wall of theplug 4 around thecylindrical seat 45. - In this manner the
heating element 2 and theplug 4 are constrained to each other with two degrees of freedom. That is to say, theheating element 2 can rotate only with respect to theplug 4, around the axis of thepin 54. Thus any translating movement of theheating element 2 with respect to theplug 4 is prevented by the coupling of thepin 54 of the bridge inside thecylindrical seat 45 of the plug. - Thus the assembly of the diffusing device is simplified, thanks to the fixed position of the heating element with respect to the plug. In fact the outer shell can easily be coupled with the
plug 4 and theheating element 2. Moreover, it must be considered that it is possible to have a rotating coupling between the plug and the outer shell and a fixed coupling between the heating element and the outer shell, precisely because the heating element is coupled rotatably with respect to the plug. - Hereunder like or corresponding elements to those already described are indicated with the same reference numerals and detailed description thereof will be omitted.
- A plug and heating element assembly according to a second example not covered by the claims, denoted as a whole with
reference numeral 100, is described inFigures 5-7 . - The
heating element 2 and theplug 4 of theassembly 100 are substantially the same as those of theassembly 1 of the first example. Abridge 5, substantially the same as that of the first example, is coupled rotatably to theplug 4. Arectangular plate 150 which extends upward on a plane at right angles to the plane of thepoles 41 of the plug is connected to thebridge 5. The top end of theplate 150 is fixed to the front surface of thebody 20 of the heating element. - The
plate 150 can be made of plastic material and coupled to thebridge 5 fixedly or rotatably. - A printed
circuit board 151, on which is mounted aswitch 152 that can be operated by the user, is fixed on theplate 150. Other optional devices, such as light devices (LED, lamps) and/or timers can be mounted on thecircuit board 151. - A plug and heating element assembly according to a first embodiment of the invention, indicated as a whole with
reference numeral 200, is illustrated inFigures 8-10 . - In this case the
poles 241 of theplug 4 are flat in accordance with United States standards. Theheating element 2 comprises aparallelepiped body 20 inside which theelectrical resistances 23 are disposed. Twoseats 230, substantially U-shaped in cross-section, able to receive and to guide theelectrical wires 42 from thepoles 241 to theresistances 23, protrude from thebody 20. - The
body 20 has acircular connection 229 in which acylindrical tang 222 defining ahole 221 to receive the wick is mounted rotatably. Thetang 222 acts as a heat regulating element and for this purpose it has aslot 228 for the passage of the heat from theresistances 23 to the wick. In this manner, the flow of heat toward the wick is regulated by rotating thetang 22. - As shown in
Figure 11 , two outer shell halves 207, 208 are mounted on theassembly 200. Thefirst shell half 207 is coupled rotatably to theflange 43 of the body of theplug 4 and thesecond shell half 208 is coupled to theheating element 2 and to thefirst shell half 207. The two half shells define ahole 209 designed to be disposed in register with ahole 221 which receives the wick. Ahole 210 to favour the diffusion of the volatile substance is formed in the front surface of theshell half 208. - Assembly of the diffuser device is extremely simple and can be done automatically, precisely because the heating element is fixed integrally to the plug. After assembly of the outer shells 107 and 108, the weakened
part 206 of thebridge 205 is cut with a tool so that the heating element is free from the plug and can therefore rotate with respect to the plug according to the arrangement of the electrical socket. - The
body 20 of theheating element 2 is connected to thecircular flange 43 of theplug 4 by means of a substantially L-shapedbridge 205. In this manner the axis of thetang 222 of the wick is maintained substantially parallel to the plane of theflange 43 of the plug. - The
bridge 205 fixedly connects theheating element 20 to theplug 4. Thus thebridge 205 has reinforcingflanges body 20 of the heating element and on thecircular flange 43 of the plug. The elbow part of thebridge 205 has a weakeningportion 206 having a reduced thickness so that it can be broken easily. - In
Figures 8-10 asingle bridge 205 has been illustrated; however, it is obvious that a plurality ofbridges 205, distributed on thecircular flange 43 of the plug and on the front surface of thebody 20 of the heating element, can be foreseen. - In
Figures 12 and 13 a plug and heating element assembly according to a third example - indicated as a whole with reference numeral 300 - is illustrated, in which theplug 4 and theheating element 2 are substantially the same as those illustrated in the first and in the second examples. - In this case the
plug 4 and theheating element 2 are connected by aremovable bridge 305. Thebridge 305 has at it ends twopins 354 and 354' designed to engage, in a snap coupling relationship, in aprotrusion 325 of the heating element and in atang 345 disposed in the rear surface of theplug 4. - In this manner the
bridge 305 keeps theheating element 2 and theplug 4 fixed in place during their movement and can be removed before the assembly thereof inside the shell of the diffuser, so as to be able to be reused or to be sent for disposal. - In the above described embodiments of the invention, the heating element and plug assembly can be disposed in plastic trays with special preformed seats. Thus mechanical arms, robots or gripping and placing arms are responsible for picking up the assembly and for placing it correctly inside the outer shell of the diffuser device. This operation is possible thanks to the fact that the heating element is connected to the plug.
